Abstract
The invention discloses a method for controlling stony desertification through watercourse sludge. The method includes the steps that coal ash is added to the watercourse sludge to be mixed evenly, the mixture is placed indoors for 5-10 days, the water content is made to reach 45-70%, the mixture is made to be balls through a mold, roots of seedlings of pioneer plants are buried in the balls, and the balls are evenly placed to the stony desertification areas. The method has the advantages that a large amount of watercourse sludge is processed, the problem that environmental pollution is caused when sludge is dumped to seas or used for land filling can be solved, the problem that plants are difficult to plant due to soil depletion of the stony desertification areas can also be solved, resource utilization of the watercourse sludge is achieved, resources are saved, the environment is protected, and good social and economic benefits and wide application prospects are achieved.
Description
Technical field
The invention belongs to environmental protection technical field, be specifically related to a kind of method of administering stony desertification.
Background technology
Under stony desertification (Stony Desertification) refers to the natural background of extremely growing at the torrid zone, moistening, the subhumid climate condition in subtropics and karst, disturb by human activity, surface vegetation is wrecked, soil is caused seriously to run off, the land deterioration phenomenon of the exposed or gravel buildup of basement rock large area is also the extreme form of karst area land deterioration.China's stony desertification mainly occurs in centered by the Yunnan-Guizhou Plateau, North gets southern foot, mountain range, the Qinling Mountains, reaches Guangxi Basin in the south, and to Hengduan mountain range, the karst area in Luoxiao mountain range west side is supported in east.Administrative scope relates to Guizhou Province, Yunnan, osmanthus, Hunan, Hubei Province, Chongqing, river and Yue8Sheng (district, city) 463 counties, area 107.1 ten thousand square kilometres, karst area 45.2 ten thousand square kilometres.By the end of the year 2011, stony desertification soil, the karst area gross area is 1200.2 ten thousand hectares, account for 26.5% of karst land area, 11.2% of territory, occupied area area, relate to Hubei, Hunan, Guangdong, Guangxi, Chongqing, Sichuan, Guizhou and township of 5575, county, 455,8, Yunnan province (district, city).
At present, afforestation is the best mode administering stony desertification, also be mode the most common, by the measure of afforestation, conceding the land to forestry, rebuild the ecological protective screen, reduce water and soil loss, thus delay the formation of stony desertification, plant generally selects the pionner that can grow in stony desertification region that is drought-enduring, happiness calcium.But because the plantation difficulty of plant is comparatively large, success rate is often lower.
The sediments that bed mud is rivers, lake, the water bottom such as reservoir and bay are accumulated for a long time, is the important component part of the heterogeneous ecosystem of water body, belongs to environmental contaminants at extensive space and the habitat in the permanent time.Bed mud is also benthic main life area and food source.Because river/lake is faced with the pollution in external point source and source, face, pollutant is easily deposited on bottom water system by the mode of precipitation, thus makes to be rich in nutrients in bed mud, comprises the element such as nitrogen, phosphorus.In processes such as the biological concentration in water body, food chain amplifications, the nutrition of mud will become more diversification.At present, the pollution problem in river course/bottom mud in lake has become the problem of extensive concern, and such as at present reservoir area of Three Gorges is slowed down due to current, and a large amount of silt and dirt are deposited on bottom reservoir area, cause comparatively serious pollution.Therefore question of common concern is treated as to the utilization of river bottom mud.
Summary of the invention
Technical problem to be solved by this invention is just to provide a kind of method utilizing riverway sludge to administer stony desertification, and it can solve the planting problem in Rocky Desertification Control, can realize again the utilization process of river course/bottom mud in lake, reach the object of protection of the environment.
In order to solve the problems of the technologies described above, the invention provides a kind of method utilizing riverway sludge to administer stony desertification is: in riverway sludge, add flyash, mix, 5-10 days is placed at room temperature environment, its moisture content is made to reach 45-70%, make spheroid with mould, then the rice shoot root system of pionner is imbedded in spheroid, evenly discharge in stony desertification region.
The present invention utilizes riverway sludge, in conjunction with flyash, selects the pionner adapting to Rocky Desertification Region, realizes the quick plantation of Rocky Desertification Region pionner, thus achieve the improvement of stony desertification.
The invention has the beneficial effects as follows: not only solve the process problem of a large amount of riverway sludge and mud ocean and throw the problem of environmental pollution that mud or land landfill cause; simultaneously; can also solve because Rocky Desertification Region soil depletion causes the problem of planting difficulty; realize the recycling of riverway sludge; both economized on resources; protection of the environment again, has good economic results in society and wide application prospect.
Embodiment
Design of the present invention is: utilize the glutinous grain of river course/bottom mud in lake and the content of organic matter high, the feature that osmotic coefficient is low, in conjunction with the difficulty that the planting of current Rocky Desertification Region exists, river course/bottom mud in lake is made pelletiod Nutrition Soil, and heeling-in can administer the pionner of stony desertification.Pelletiod Nutrition Soil directly can be sowed in Rocky Desertification Region, or adopt the mode of spreading manuer in holes to sow, pionner utilizes the nutrient component in the Nutrition Soil made by bed mud, stablized and grown, and then by the dilating effect of root system, realize the immobilization in Rocky Desertification Region, thus realize the fast and stable growth of Rocky Desertification Region pionner, promote that the vegetation of regional stony desertification is improved.
The invention will be further described below:
This method invention is: in riverway sludge, add flyash, mix, and places 5-10 days at room temperature environment, its moisture content is made to reach 45-70%, make with mould the spheroid that diameter is 2-3cm, then the rice shoot root system of pionner is imbedded in spheroid, evenly discharge in stony desertification region.
Above-mentioned flyash is receive in the flue gas after coal combustion to catch the thin ash got off, and the mass ratio that flyash accounts for spheroid weight in wet base is 10%, by mixing of flyash and mud, reduces the moisture content of mud fast, the plasticity of raising mud.
Happiness calcium, the drought-enduring plants such as above-mentioned pionner seed selection Chinese prickly ash, Chinese toon, fiery sour jujube, the bark of eucommia, paper mulberry, honeysuckle; Pionner seedling individual plant height is not higher than 20 cm.
Above-mentioned evenly discharging is sowed or two class planting patternss of spreading manuer in holes for shedding.
